We are   the  first  private  enterprise  that  is  engaged  in  the  design  and manufacture of electro-hydraulic  servovalve  in  China.  At  presentï¼ÂŒits  products  includes  HTPL801ï¼ÂŒHTPL802ï¼ÂŒHTPL803 and  HTPL808  Double  Flapper-Nozzleï¼ÂŒTwo Stage Electro-Hydraulic  Flow  Control  Servovalves  as well as  HTS818  Three  Stage  Electro-Hydraulic  Flow  Control  Servovalve.

The  valves  above  mentioned  are  applicable  for  controlling  positionï¼ÂŒvelocityï¼ÂŒacceleration  and  force  of  electro-hydraulic  servo  control  systemï¼ÂŒwhich  is  widely  applied to  various  fields  such  as  metallurgy, light  industry  and  engineering  mechanismï¼ÂŒmachine  buildingï¼ÂŒlarge  scale  test  facilityï¼ÂŒaerospaceï¼ÂŒshippingï¼ÂŒradarï¼ÂŒrtillery  and  etc.  Those valves can replace domestic  FF  series  servovalve  or  imported  MOOG  series  servovalve.
